ATTORN EY Patented Jan. 28, 1936 UNITED STATES PATENT OFFICE 2,029,978 FILTERING DEVICE James Aaron Matney, Prosser, Wash.

Application June 19, 193.4, Serial No.'73l,3'l 1 Claim. (Cl. 210-131) This invention relates to filters and its general object is to provide a filtering device that is primarily designed for use with the lubricating system of an engine, and it not only includes filtering means, but also magnetic means, the latter being adapted to remove metallic particles from the lubricant as it passes through the device, therefore the lubricant will be free from foreign matter, which of course will result in better lubricating qualities for a longer period of time than is possible with the ordinary filter now iii general use.

A further object of the invention is to provide a filter that includes removable parts and ready access can be had thereto for. removing the parts for cleaning and replacing the same when necessary.

Another object of the invention is to provide a inter of the character set forth, that is simple in construction, inexpensive to manufacture, easy to install and extremely efiicient in use and serv-j ice.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a longitudinal sectional view taken through the filter which forms they subject matter of the present invention.

Figure 2 is a sectional view taken approximately on line 2-2, of Figure 1, looking in the directionof the arrows.

Figure 3 is a sectional view taken approximatemately on line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is a perspective view of the frame vigilich constitutes a holder for the filtering mater Figure 5 is a detail view of one of the clamping members for the magne Referring to the drawing in detail, the-refer-- 3, as clearly shown. in Figure l of the drawing.

The cap has formed therewith or otherwise secured thereto and extending centrallytherefrom a nipple I which provides the inlet for the container. A nipple 5 extends from the closed end 2 and preferably for the upper end thereof to provide the outlet for the container.

Removably disposed within the container I and 5 adjacent one end thereof as best shown in Figure 1, is a magnet 6 of the horse shoe type and which as shown is in the form of a sleeve having a relatively wide gap 1 extending longitudinally thereof to provide the poles 8 of the magnet, as 10 will be apparent. Surrounding the magnet is a sleeve 9 of suitable insulating material, so as to insulate the same from the wall of the container.

A suitable gasket I0 is disposed between the cap land the containerto not only provide a leak 16 proof connection but also to-insulate the magnet from the cap.

Any well known filtering material may be used with my device, but I preferably employ a sheet of coarse woven cotton fabric which is arranged 20 in a roll H and disposed within a skeleton frame of a size and shape to fit within the container and the frame includes split rings I2 that are connected at intervals in their circumference by cross rods i3, the frame acting as a'means for holding the filtering material in roll formation as well as to allow for its easy insertion and removal with'respect to the container.

The split rings i2 have hooked ends as best shown in Figure 4 so that the rings can be arranged in clamping association with the roll of filtering material.

It will be noted from Figure 1 that the filtering material has one end arranged in contacting en gagement with the confronting endof the magnet to assist in holding the latter firmly within the container, but I also employ spring clamps such as shown in Figure 5, and these clamps ter niinate in ears N that engage the sides of the poles of the magnet, while arranged midway between the ends of the spring clamps are humped portions ii that engage the inner wall of the container, with the result the magnet will be held against movement or casual displacement. A disk 16 of screen wire engages the opposite end of the filtering material and is held accordingly through the instrumentality of a collar I1 that contacts with the closed end of the container as clearly shown in Figure 1. i 5 From vthe above description and disclosure of the drawing, it will be obvious that I have provided a filtering device to be used with the lubrieating system of an engine and is capable of removing practically all foreign matter from the 56 lubricant, due to the magnet and the filtering material, and all of the parts within the container."

can be removed therefrom, so that they can be readily cleaned when necessary. By providing a sheet of cloth in rolled formation forthe filtering material, it will beapparent that it can be readily cleaned merely by unrolling the sheet andwashing the same in some suitable cleaning fluid such as gasoline or the like. However, the filtering material can be made from layers of cloth stitched together. The remaining parts of the filtering device can be made from any suitable aoaeme vided that such change; fall within the. scope or the appended claim.

What I claim is: A filtering device comprising a container,- inlet means and outlet means therefor, magnetic means in said container and being insulated therefrom, means for detachably'securing the magcontainer, a skeleton wire frame for the filtering material and including split end rings, means'for gether, cross rods having their ends secured to the rings, said frame and filtering material being removable from the container as a unit, screening means cooperating with the filtering material, and means for holding the screening means against one end of. the filtering material and spaced from the outlet means.
